Greenpeace’s Ocean Campaign focuses on ocean threats including industrial fishing, bycatch, human rights at sea, habitat impacts, and works to improve fishery management. Greenpeace evaluates U.S. retailers on traceability and other sustainability issues through its Carting Away the Oceans reports, and assesses canned tuna brands through its Tuna Shopping Guide. Greenpeace released Sea of Distress, its first evaluation of seafood sustainability among U.S. foodservice management companies and broadline distributors. Greenpeace is working to address transshipment at sea, inadequate observer coverage, insufficient monitoring, and control and surveillance regimes, which the organization has identified as major barriers to traceability efforts. Greenpeace also houses an IUU vessel blacklist on its website, which combines evidence from its own investigations with a compilation of official listings from around the world.
